ABSTRACT:
A method for distributing encryption keys for use in communication systems such as trunked radio communication systems. Group traffic keys are encrypted at a key administrator and passed to a distribution facility for storage and distribution. The distribution facility passes the encrypted group traffic key to communication devices where the group traffic keys are decrypted and used to encrypt/decrypt traffic.
